Pratt & Whitney intends to replace faulty engines of 40 IndiGo planes by June 2026.

This move will potentially boost IndiGo's profitability this year and next, depending on the pace of engines replacement, reducing the carrier's reliance on costly leased planes to offset the nearly-10% unused aircraft on its fleet.

The airline flies two of three passengers in India.

Forty planes with Pratt & Whitney engines are grounded while 60 are flying.

“There is an assurance for a staggered improvement in the aircraft on ground situation with a June timeline,” the first person said on the condition of anonymity, as the discussions between the world’s secondlargest commercial aircraft engine maker and IndiGo are private.
